Condition: Obstetrics & Gynecology / Reproductive & Hormonal Disorders
Investigator: S. Zev Williams, MD, PhD
Status: Closed
Researchers at Columbia are looking at new treatments to help delay the start of menopause. This is a randomized trial where some women will receive medication and some will receive a placebo. The study will last approximately 12 weeks, followed by monthly follow-ups for 6 months. Participants will be compensated $1300 for compensation.
Condition: Autoimmune Disorders / Rheumatoid Arthritis
Investigator: Jon Giles, MD
Status: Closed
We are inviting patients with active Rheumatoid Arthritis (RA) to help us better understand how treatment options affect inflammation in soft tissues. With a combination of blood work, a full-body FDG PET-CT scan, questionnaires, and a soft tissue biopsy (from an area around the belly button), we hope to see how RA interacts with these multiple areas of…
Condition: Autoimmune Disorders / Rheumatoid Arthritis
Investigator: Laura Geraldino-Pardilla, MD, MPH
Status: Closed
This study aims to understand how two commonly prescribed drugs impact myocardial inflammation in rheumatoid arthritis.
Condition: Obstetrics & Gynecology / Reproductive & Hormonal Disorders
Investigator: Rogerio Lobo, MD, FACOG
Status: Closed
The purpose of this study is to evaluate a new experimental (investigational) oral combination hormone drug product containing estradiol (a form of the estrogen) and progesterone (a female hormone that regulates the inner lining of the uterus called the endometrium) for postmenopausal women who have hot flushes. The estradiol and progesterone used in this…
Condition: Lung Disease / Pulmonary Hypertension
Investigator: David Lederer, MD
Status: Closed
The purpose of this study is to study the effects of a new study drug known as Riociguat in people diagnosed with pulmonary hypertension (PH) associated with idiopathic interstitial pneumonia (IIP). Patients will be in the study for approximately 26 weeks in which they will take the pill Riogciguat three times a day.
Condition: Lung Disease / Pulmonary Hypertension
Investigator: Erika Berman-Rosenzweig, MD
Status: Closed
This is a clinical research study designed to determine the safety and effectiveness of the TIVUS system, an investigational device used in the treatment of PAH. The TIVUS System is intended to treat patients with pulmonary artery hypertension by injuring the sympathetic nerves surrounding the pulmonary vasculature (denervation) using ultrasonic energy. The…
Condition: Autoimmune Disorders / Rheumatoid Arthritis
Investigator: Joan Bathon, MD
Status: Closed
The study aims to compare the effect two different RA treatments on cardiovascular health in patients who are considering a treatment change. The study is recruiting patients who are only taking methotrexate and are switching treatment due to a lack of improvement. The trial will randomize participants to take a TNF inhibitor (Enbrel or Humira) in addition…
Condition: Lung Disease / Pulmonary Hypertension
Investigator: Elana Bernstein, MD
Status: Closed
This study involves two infusions of either rituximab or placebo, two right heart catheterizations (6 months apart), and a variety of other clinical study procedures and exams.
Condition: Autoimmune Disorders / Rheumatoid Arthritis
Investigator: Joan Bathon, MD
Status: Closed
We are doing a research study to learn more about why people with rheumatoid arthritis (RA) are prone to heart disease. We are recruiting patients diagnosed with Rheumatoid Arthritis without a personal history of heart disease. This study involves one initial full visit as described below, and a brief follow up visit that will take place approximately 2 or…
